FAQ
Do I need tuning with this nozzle?Yes. While the truck may run on stock calibration, custom tuning is strongly recommended to optimize timing, pulse width, and rail pressure for power, drivability, and safe EGT.
Will this work with stock turbo and CP3?It fits physically, but to realize ~350 HP potential you’ll want a healthy CP3/lift pump and a higher-flowing turbo. Stock hardware may limit gains and raise EGT.
Is this a single nozzle or a set?This listing is for one nozzle. For full engine upgrades, order a quantity of six or shop our complete injector options.
Is this emissions compliant?Intended for competition/off-road use where permitted. Verify local, state, and federal regulations before purchase/installation.
